*I am a newbie on osg.
My laptop's OS is ubuntu11.10 with AMD ATI HD6770. I've enabled 3D
accellerate driver.
I've compiled and installed osg3.01 successfully. Here is result:

Hi Peterakos,
How you would tackle the problem depends upon what your need are for
changing the number of uniforms.
In terms of OpenGL objects it's generally best to used fixed size objects
so that you don't have to reallocate them. To change the size used by
the shader one would simply pass in
H Shawl,
The OSG supports multi-texturing, simply assign each texture to its own
texture unit. See the osgmultitexture example and osggeometry examples to
see how to assign multiple textures and set up text coords.

Hi Li? Zhenpeng? Could you sign with the name you wished to be address as.
Thanks.
There looks to be two separate classes of problems - missing dependences
(peg and freetype) and the X11 error.
To solve the dependencies issues you'll need to pull in the dev packages, a
list of the most common
Hello!
I am creating an osg scene, which is rendered to a .NET picture box on a
windows forms scene.
Code:

HWND hwnd = (HWND)wh;
baseViewer = new osgViewer::Viewer();

hi robert,
Thanks for your concern.
For my sign name, I will change it to keep same between google+ and osg
forums. It's convinient to us all.
For your advice, I will load the dependencies and rebuild osg.
Could you please give me some more advice about X11 error? It's confusing
and hard to
Hi Li,
Just a long shot... have you tried to set LD_PRELOAD to your libGL.so
library. I have had similiar problems in the past with the old ATI drivers
as well as the Mesa drivers. Something like export
LD_PRELOAD=/usr/lib/libGL.so could do the trick. Anyway check your
environment variables with

Hi Jan,
Yes, preloading an incorrect version of the library will only give you more
problems, that's the reason why I said to check the environmet variables.
BUT in older versions of Ubuntu and with Mesa drivers there was a bug with
the DRI drivers not linking to the libGL library see [1] and
Hi Jordi,
That's great. I believe you find the issue I encountered.
Following is my check result.
*env | grep -in libgl*
14:LIBGL_DRIVERS_PATH=/usr/lib/fglrx/dri:/usr/lib32/fglrx/dri
That means no variable pointing to my libGL drivers. I checked /usr/lib
directory and there is no libGL.so file.
Hi Li,
Have you compiled OSG in 32 or 64 bit? Check if in /usr/lib/fglrx/dri or
/usr/lib32/fglrx/dri do exists libGL depending on your target architecture.
As Jan said a the output of glxinfo could give some light. libGL is
supposed to be installed/replaced with your drivers.
Cheers.

Thanks for your concerns. Your advice is very helpful.
In fact my ubuntu is for 64bit target. I checked file attribute as follow:
*file /usr/lib/fglrx/libGL.so*
/usr/lib/fglrx/libGL.so: symbolic link to `libGL.so.1'
*file /usr/lib/fglrx/libGL.so.1*
/usr/lib/fglrx/libGL.so.1: symbolic
It seems like you have a bad installation of your fglrx drivers. Reinstall
them. In the other hand I was asking about which was your OSG compilation
target. I assume 64 bits.
Hope it helps.

Martin, all.
That is indeed great news, but we would need to maintain Qt4 compatibility
for a number of years ahead. It also confirms the idea of a base-class in
osgQt::GraphicsWindowQt::WindowData that would be inherited by various
implemtations, where one would be Qt4, one Qt5 and one with

Hi.
I'm using SoftShadowMap. I've tried to change jittering scale, but couldn't
get rid of shivering/moving of shadow with it.
Here's the video that depicts the shivering:

Is there any way to remove that shivering, or at least reduce it?
Thanks.
Hi,
I am using osg to display just a simple cube using lines in 3D. This is fine
if I use a solid line (no pattern). but I get an odd effect when I use
linestipple to create a dashed line. When I move the camera around the dashes
move up/down the length of the line. This looks wrong to me.
Hello !
I d like to know what version of ffmpeg I have to use to compile osg 3.0.1
in linux ?
Thanks

Hi, OSG 3.0.1 and ffmpeg 0.8.4 work with this tiny patch:

or you could just upgrade to the latest
Hi Darren,
This will be a limitation with the implementation line stipple in OpenGL.
I can't think of an easy solution to making sure the stipple is object
space, the hard way would be to not use LineStipple but create the lines
yourself and then use a 1D texture to create the stipple effect.
create the lines yourself and then use a 1D texture to create the stipple
effect
are there any examples I can look at?
Cheers,
Darren

Hi all,
Just to say I have tested OSG(SVN) under Windows 8 Pro(x64) and haven't
noticed any problems.
It's still technically Windows 7 apart from the 'Start' button going and is
now the metro interface and you are no longer able to find anything, until
you get used to it. It seems to work fine!

Plenty, just search the OpenSceneGraph/examples for Texture1D. One obvious
